Resistance of tomato cultivars to Tuta absoluta (Lepidoptera: Gelechiidae) under field condition

Tomato leaf miner, Tuta absoluta, is the most destructive pest of tomato in Iran. Resistance levels of six tomato cultivars to the pest damage were evaluated during two tomato growing seasons (۲۰۱۴-۲۰۱۵). Samplings were done weekly. Leaf and fruit damages as well as the total yield of the cultivars were compared. Furthermore, leaf trichome density was evaluated. The highest to lowest leaf infestation rates were recorded for the Primo early, CaljN۳, Petomek, Rio grande, Early urbana and Super ۲۲۷۰ cultivars respectively. Fruit infestation rate in Early urbana was significantly lower than the other cultivars in both growing seasons. Total yield of tomato (from the highest to the lowest) belonged to Super ۲۲۷۰, Early urbana, Rio grande, Petomek, Calj N۳ and Primo early cultivars.
